FIGS. 1-6 illustrate one example of a portable radio 10. As illustratedin FIGS. 1 and 2, the portable radio 10 includes an outer housing 14,for example a rigid outer housing made of plastic. The outer housing 14includes a speaker bezel 18 positioned along a front of the portableradio 10. The portable radio 10 also includes a button 22 that ispositioned within an opening defined by the speaker bezel 18. A portionof the button 22 is exposed to an environment outside of the portableradio 10 and is visible when the speaker bezel 18 is attached to therest of the portable radio 10 (FIG. 1).

With reference to FIGS. 3-6, the button 22 is movable, generally towardan interior of the portable radio 10 and away from the interior. In someembodiments the button 22 is biased (for example with a spring) in adirection away from the interior of the portable radio 10. In theillustrated embodiment the button 22 includes an outer region 26 (forexample generally rectangular in shape) that may be pressed by the userduring use. The button 22 further includes an inner region that extendsfrom the outer region 26 and includes a plunger 30 (FIGS. 5 and 6). Theplunger 30 is a projecting region of the button 22 that moves inwardlytoward the interior of the portable radio 10 when the button 22 ispressed. The button 22 may have other shapes and sizes than thatillustrated.

With continued reference to FIGS. 3-6, the button 22 is electricallycoupled to a printed circuit board 34 within the interior of theportable radio 10. In the illustrated embodiment the portable radio 10includes a frame 38 positioned in front of (i.e., exterior to) of theprinted circuit board 34. A speaker 42 (FIGS. 5 and 6) is positionedwithin the frame 38. A support platform 46 is positioned in front of thespeaker 42 and the frame 38. A portion of the support platform 46 ispositioned over the speaker 42, and includes speaker ports 50 (FIG. 3).As illustrated in FIG. 3, antenna elements 54 (for example sheet metalantenna elements) may be positioned on regions of the support platform46 adjacent the speaker ports 50. The antenna elements 54 may beelectrically coupled to the printed circuit board 34 (for examplethrough a separate electrical path other than that for the button 22).

With continued reference to FIGS. 3-6, the portable radio 10 includes aset of electrical components that are linked between the button 22 andthe printed circuit board 34, such that a signal may be sent from thebutton 22 to the printed circuit board 34. In some embodiments, theportable radio 10 includes at least two, three, four, or in some casesat least five separate electrical components that are separately coupledto one another between the button 22 and the printed circuit board 34.In some embodiments, the electrical components cause the electricalsignal to change directions at least two times, three times, or in somecases at least four times as the signal moves through the electricalcomponents between the button 22 and the printed circuit board 34. Thebutton 22 may be movable between a first position where the electricalsignal is sent through the electrical components to the printed circuitboard 34, and a second position where the electrical signal isinterrupted.

In the illustrated embodiment, the set of electrical components includesan electrical flex element 58 coupled to the support platform 46 and tothe frame 38. The electrical flex element 58 includes a first region 62adhered to the support platform 46, and a second region 66 adhered tothe frame 38. The electrical flex element 58 further includes a bentregion 70 (for example a thin, curved strip) disposed between the firstregion 62 and the second region 66. As illustrated in FIGS. 3 and 5, thefirst region 62 extends along a first plane, and the second region 66extends along a second plane that is perpendicular to the first plane.The bent region 70 is non-planar, and curves from the first plane to thesecond plane. In the illustrated embodiment the first plane isperpendicular to a direction of movement “D” (FIGS. 4 and 6) of thebutton 22, and the second plane is parallel to the direction ofmovement.

With reference to FIGS. 5 and 6, the set of electrical componentsfurther includes a tactile dome 74. The tactile dome 74 is positionedbetween the plunger 30 of the button 22 and the electrical flex element58, and may have a dome-like or other shape that provides tactilefeedback when pressed and released. When the button 22 is in a firstposition the tactile dome 74 is in a compressed state (is pressed down)and is in contact with the electrical flex element 58 for example tocomplete the electrical connection, and when the button 22 is in asecond position the tactile dome 74 is in an uncompressed state (israised up) and is out of contact with the electrical flex element 58 forexample to interrupt the electrical connection. In some embodiments, andas illustrated in FIGS. 5 and 6, the portable radio 10 may also includea secondary plunger 78 (for example made of silicone) that is disposeddirectly behind (interior of) the plunger 30 of the button 22, and ispositioned between the plunger 30 of the button 22 and the tactile dome74. The secondary plunger 78 may form part of a larger siliconestructure (or structure made of other soft material) that is coupled tothe support platform 46.

With reference to FIGS. 3 and 4, the set of electrical componentsfurther includes a spring clip connector 82 that is coupled to thesecond region 66 of the electrical flex element 58, as well as a contactfinger 86 coupled to the spring clip connector 82. The spring clipconnector 82 is disposed between the electrical flex element 58 and thecontact finger 86. In the illustrated embodiment the contact finger 86has a ninety degree bend, although other embodiments include differentshapes and sizes than that illustrated.

With continued reference to FIGS. 3 and 4, the set of electricalcomponents further includes a pogo 90 coupled to both the contact finger86 and to the printed circuit board 34. The pogo 90 extends in anelongate direction that is parallel to the direction of movement D ofthe button 22. The pogo 90 is disposed within a pogo housing 94, andslides within the pogo housing 94.

During use, when the button 22 is pressed the plunger 30 of the button22 contacts and presses against the soft, secondary plunger 78, which inturn presses against the tactile dome 74. The tactile dome 74 iscompressed, causing the tactile dome 74 to contact the first region 62of the electrical flex element 58. This contact allows a signal to besent through the electrical flex element 58, through the spring clipconnector 82, through the contact finger 86, and through the pogo 90 andinto the printed circuit board 34. The signal thus passes throughvarious different electrical components, and changes direction as ismoves generally from the button 22 on the exterior of the portable radio10 to the interior of the portable radio 10 and to the printed circuitboard 34.

In some embodiments, the portable radio 10 is interactive. For example,the button 22 may be a voice control button for establishing voicecommands and information exchange with the portable radio 10 when thebutton 22 is pressed, although the button 22 may be used for any of anumber of different purposes (for example power control, volume control,and the like). In the illustrated embodiment, when the button 22 ispressed a voice may emanate from the speaker 42. For example, the voicemay say “Can I help you?” and the user may then ask the portable radio10 a question (for example asking the portable radio 10 to run a licenseplate check, or to provide information regarding traffic conditions at aparticular location). The portable radio 10 may then respond with therequested information.

With reference to FIGS. 3-6, in the illustrated embodiment the button 22may be exposed to water and other outside environmental conditions,whereas the speaker 42 may be sealed from water within the frame. Forexample, the secondary plunger 78 and/or the tactile dome 74 may besealed (with adhesive) to the first region 62 of the electrical flexelement 58 (for example via a perimeter seal), and as described abovethe first region 62 may itself be sealed (with adhesive) to the frame 38and to the support platform 46. As illustrated in FIGS. 3-6, in someembodiments a debris pad 98 is also coupled to the button 22. A portionof the debris pad 98 is positioned adjacent the plunger 30 of the button22, and a portion of the debris pad 98 is in contact with an outersurface of the speaker bezel 18. Additionally, and with reference toFIG. 5, in the illustrated embodiment the portable radio 10 may includean air vent 102 disposed on the support platform 46. The air vent 102permits passage of air from behind (interior of) the button 22 to anopen region disposed behind the support platform 46.
